Chemistry: Limestone to Clay Ratio

  1. Mar 31, 2013 #1
    1. The problem statement, all variables and given/known data
    1) If limestone (calcium carbonate) and clay (assume aluminum silicate) are mixed together and heated then the result is cement. Cement is a mixture of calcium oxide, carbon dioxide, aluminum oxide, and calcium silicate. These bags can be purchased at any building supplies store. Write the balanced equation for this reaction.

    2)If the factory has 100.0 kg of clay in its reaction vessel, then how much limestone will they need to exactly react with the clay to produce the cement?


    2. Relevant equations



    3. The attempt at a solution
    1) answr. 4CaCO3+Al2(SiO3)3 -> CaO+4CO2+Al2O3+3CaSiO3

    2) I don't know where to even begin!

    You can use the chemical equation you have written. The reactants always react in a constant ratio of masses. And that ratio of masses can be found from the chemical equation.

    kg>g>mol for a start.

    clay = aluminum silicate
